Do you think the Psion will get a third UA?
So far they give each new subclass 1 or 2 tries before being published or discarded (like what happened to the purple dragon knight fighter). Consider this is an entirely new class, do you think WOTC will give it a third attempt at a UA, or considering that since the last one was generally accepted they will just go ahead with the data they currently have?
For the matter I do wish they give it another go on Unearted Arcana. There were still things I wished were more refined, and would prefer for the community to have one last chance to give our opinions. If its delayed thats ok for me, preferable for it to arrive late than publish it with a few hinges that keep it from being better.
